Apple’s Senior Vice President of Software Development Craig Federighi recently gave an interview to the British edition of The Independent. He shared some details about the extreme tests that Coopertinos expose their chips to.
According to Federiga, all Apple processors, starting with the Apple T1, Apple S2 and Apple A7 have an additional chip called Secure Enclave. The latter is responsible for all data protection operations and guarantees their integrity even in the event of a kernel security breach.
Apple puts Secure Enclave to the most severe tests: heats the chips to 110 and cools to -40 degrees Celsius. Despite the fact that the iPhone can rarely get into such conditions, in Cupertino are confident in the need for such checks. According to Craig Federighi, Secure Enclave should work in a variety of conditions, because otherwise vulnerabilities in the chips will be exploited by attackers.
In general, such tests are not surprising. According to the available data, Coopertinos try to test all their products in a variety of conditions. Especially for this purpose, the company has a large number of closed laboratories, which conduct all tests.
